'some' expressions? does this mean to say that the recordings are so bad that they become unusable, or do they mean that the checklists were only partly complied with?? That sentence is extremely vague and yet the CVR recordings could shed some light on the sequence of events...
It seems to be a bit of both.
The CVR is both, of extremely bad quality in the inmediate moments previous to the accident to the extend that most of it can only be made sense of using foreinsic methods (carried out by the police sound lab, and therefore not 100% conclusive) and the checklist (unofficially) seems not to have been done 100% according to regulation, but pretty close. (i.e. flaps and slats may have been reported as "ok" rather than as "11º, takeoff").
It seems, that because the audio can not be fully made out, it can also not be conclusive whether the checklists were done 100% right, 99% right, or what, but they (unofficially) seem to be "possibly not perfect, but reasonably good". In another words, the pilots probably THOUGHT they had gone through it and they probably THOUGHT they had the flaps and slats set.
The "almost exact" transcript of the CVR will probably be known (outside the authorities) in a couple of weeks. It will then shed some light on exactly how distracted the pilots could've been during the maneouver and how closely they followed the checklist.
The judge will spend the next days calling a couple dozen witnesses, 6 on the 17th, 5 on the 27th, 5 on the 31st, some of them for the second time, to ask specific questions and check their declarations against their first ones. He will concentrate on the technicians that did the "repairs", the previous failures of the aircraft and how it could've affected the TOWS.
He'll also call the flight attendant that partially witnesed the accident from the air, the airport ground coordinators, the supervisor of airplane cargo loading, the supervisors of the crew in service on that flight, etc.
The CIAIAC has informed that, as it was expected, they won't speak a word again officially in public about the accident for between 1.5 and 2 years.
Thankfully, there is a public judiciary investigation going on and I'm sure the judge will request updates and evaluations from the QAR data, the flaps handles, and other important data within the next months.
